If anyone else wants one don't get it through my ebay store. I sell here for less because of no ebay fees. I also make test pipes for 84-85. The one in spaceweasel's pic fits 86-91.
A fabrication for the '92+ C4 LT1/4 would be very complicated and require also bending equipment. L & R are very different and would require also O2 bungs.

The bending and the O2 bungs aren't a big deal. I wonder though what the difference is between the right and left side? Is it just the location of the O2 bung or are the bends different? I'm confident that if I purchased a right and left side OEM set of cats for a 92-96 that I could fabricate jigs that would allow me to make them pretty easy. The problem is cost. A set of test pipes like that would be pretty expensive compared to the test pipes for 84-85 or 86-91. I'm not sure if people would be willing to pay what i would need to charge to make it worth while. But I'm going to at least look into it.

In case anyone is wanting a 86-91 test pipe, I changed the design. I'm not making these with a flared ball end anymore. Now I'm going with a Walker graphite exhaust gasket with the proper flare and a welded on retainer. This will be much easier for me to make and should make a better seal. Also this should work with the factory length bolts.
